Description
These chlorine tablets are one of the most popular products for ensuring swimming pool water is safe and bacteria free. They are stabilised to minimise chlorine loss to sunlight. They slowly release chlorine over 3–5 days depending on the water flowing over them.
They can be used in floating dispensers, chemical feeds and skimmer baskets.
Apply regularly to achieve the recommended free chlorine level of 3-5 mg/l (ppm) for hot tubs or 1-3 mg/l (ppm) for swimming pools. These tablets are slow release and long lasting and have the minimum effect on the pH of the water for a stabilised chlorine tablet.
Key Features
Its best to operate a free Chlorine Range of 3 – 5mg/l for hot tubs and 1-3mg/l for swimming pools. These stabilised chlorine tablets are ideal for regular dosing of your swimming pool, to produce free active chlorine which kills bacteria and other potentially harmful organisms. They contain a high level of available chlorine and chlorine stabiliser.
Application Instructions
1. Maintain pH level within the ideal range of 7.2 – 7.6. If outside this range please use our PH plus or PH minus products to adjust for the best results.
2. Maintain free chlorine residuals for swimming pools between 1 – 3mg/l (ppm). Freshly filled pools require an initial shock or start up dose of chlorine: 50mg/l (ppm) for 1 hour or 20mg/l (ppm) for 2 hours.
3. For floating dispenser: Fill the floating dispenser with tablets and adjust the aperture mechanism at the bottom of the dispenser to obtain the 1-3mg/l (ppm) desired range. Alternatively keep the dispenser aperture constant and vary the tablets inside to achieve 1-3mg/l (ppm). The dispenser should be removed from the pool whilst swimmers are bathing.
4. For chlorine feeders: Fill the dispenser and follow feeder instruction manuals on flow regulation to maintain 1-3 mg/l (ppm) chlorine levels.
5. For skimmer baskets: Fill the basket with 2/3 tablets and monitor levels to maintain 1-3 mg/l (ppm) chlorine levels.
6. It is recommended that you periodically (e.g. fortnightly or after heavy use) shock dose your pool to eliminate any excess contamination.
Note: If using in skimmer baskets we would suggest you run the pump often to prevent a build up of chlorine. Please ensure children to not have access to the skimmer as this could be dangerous.
Dose Rates (subject to water flow rate and temperature)
Small pool 40,000 litres of water requires approx 1 tablet to increase the chlorine level by 1mg/l (ppm) or approx 3 tablets to increase chlorine level by 3mg/l(ppm)
Large pool 80,000 litres of water requires approx 2 tablets to increase the chlorine level by 1mg/l (ppm) or approx 6 tablets to increase chlorine level by 3mg/l(ppm)

Stupidly decided to put the 8ft pool up in the garden this year before remembering how much of a faff it is to put away again. Still, little’n loved it and i definitely made the most of it with the nice weather too. Decided to try and leave it out for a bit though and knew id need some chemicals to avoid draining and re-filling. Had no idea what i needed, or what was best, so a little online research led me to believe these were a quick win for my situation. Found this, seemed reasonably priced compared to others and reviews were ok. Arrived, popped it open, put a single tablet in and left it to float about whenever we werent using it. Pool was covered too to stop debris landing in it constantly as well.Im no expert but i think it worked a treat? Pool stayed lovely and clear, no gunk or slime build up anywhere and it smelled clean. A little chemically, like a swimming pool kinda scent, but reassuringly familiar as clean, if that makes sense. Took it out whenever we dived in, popped it back in after. I got over 3 weeks out of a single tablet which just slowly dissolved and did its thing. Testing strips were easy to use, take one out, dip it, wait for the colours to update and compare against chart. With the treatment in, my readings were always spot on so i assume it was working as intended. Despite being able to tell it had stuff in, we had no issues with burning eyes or anything like that ether. Plenty left for if we ever have more good weather too. Cant complain with this at all, simple, effective and saved me a tonne of hassle messing about with the pool. Would definitely recommend.It is advisable to remove all chemicals some 3-10 days in advance of draining though, i need to let mine drain predominantly in the garden and didnt want to kill any plants or wildlife, so after the weather turned, i took this out, left the pool covered for 4/5 days until it no longer smelled fresh and then drained. All my grass and surrounding plants are perfectly fine so seems no harm done.
